PANEL LOCK.

Application filed October 31, 1921. Serial No. 511.755.

T 0 all whom it may concern.

Be it known that we, JOHN F. Bnonow- SKI and Gnonon J. BURMEISTER, bothcitizens of the United States, and residents of Milwaukee, in the countyof Milwaukee and State of lVisconsin, have invented certain new anduseful Improvements in Panel Locks; and we do hereby declare that thefollowing is a full, clear, and exact description thereof.

The invention is a device to lock and clamp 21- panel upon a frame.

It is an object of the invention to facilitate the ready installation ofa screen for storm panels by means of a lock operating to clamp thepanel in position.

It is a further object to eliminate looseness and rattling of panels.

Further objects willbe apparent as the description proceeds.

Figure 1. shows a horizontal sectional view taken immediately above thelock.

Figure 2 shows an elevation on the line 2-2 of Figure 1.

Figure 3 is a cross section on the lines 33 of Figure 2.

Figures 4, 5 and 6 are details of the lock mechanism.

The invention is described more in detail. A door frame 1 engages with apanel frame 2, carrying a glass 3. The door frame 1 has a chamber t forreceiving the lock plate 5, having lugs 6 thereon for retention in thedoor frame and carrying a pivot- 7 thereon encircled by spi 211 spring8. Upwardly directed from said plate 5 is a flange 6 having thereon, afinger 6. Rotatably mounted on said pivot 7 is a locking member 9, shownin Figure and in dotted lines in Figure 6.

The portions of the lock nearest the observer when viewed. in Figure 2,are referred to as the upper portions. Locking member 9 has on its lowersurface two radial grooves ll). On its upper surface are shoulderportions 11. Gradually deepening grooves 11 terminate at theseshoulders. Concentrically rotatable with said locking member 9 is a diskmember 12 having two downwardly directed semi-circular flanges 13terminating in shoulders 13, and a central. upraisedboss 14:, havingtherein, a slot 15 adapted. to receive the end of a screw driver. Doorframe 1 is provided with. an aperture 16 to receive boss 14. When spring8 is in an extended position, as shown in Figure 1, pressure upon-boss14 operates to move disk 12 and locking member 9 downwardly.

It is thus apparent that when panel frame 2 is removed, the lockingpieces be placed in the position shown by insertion through theside ofchamber a, lugs 6 being forced into the wood. I

When the panel frame is placed in position to be engaged by the lockingmember, rotation of disk member 12 in a clockwise direction causesshoulders 13 to engage with shoulders 11 of the locking member 9. Thiscauses engagement of groove 10 of the locking member with finger G. Thepanel is then locked. A counter clockwise turn of the screw driver inslot 15 causes flanges 13 to ride upwardly in grooves 11, thus causingdepression of clamping member 9 and exercising a clamping action uponsurface 170f the panel frame where the" locking member contacts. Thisposition of the members, is shown in Figure 1. When it is desired todisengage the panel, a rotation of the screw driver in a clockwisedirection causes a reengagement of shoulders 13 with shoulders 11, anddisengagement of groove 10 from linger 6". The locking member 9 is thenmoved out of locking position. This releases panel frame 2.

It will be noted that locking member 9, when in the position shown inFigure 1, acts as a lever with one of its ends resting on flange 6,flanges 13 pressing upon the central portion.

We claim:

1. The combination with a locking member of a finger for engaging saidlocking member when in looking position, and means operating in onedirection to move said locking member into locking position and in theother direction to clamp said locking member in position.

2. In a panel loclgthe combination of a rotatable member, two armsthereon, each having an indentation on one face thereof, two shoulderson the other face thereof, a second rotatable member having flangesthereon cooperating with said shoulders to turn said first mentionedrotatable member in one direct-ion, and operating when turned in theother direction to clamp said first named rotatable member.

The combination of a plate, a pivot thereon, a flange extending upwardlytherefrom, a finger on said. flange, a locking member having groovestherein adapted to engage said finger, and means for moving said lockingmember into locking position and then exercising a clamping actionthereon.

4. In a panel lock, the combination of a locking member having twoindentations adapted to engage a locking finger, shoulders on saidlocking member, and grooves increasing in depth to said shoulders, adisk 10 having semicircular flanges thereon of increasing depthterminating in shoulders, and a boss on said disk having a slot thereinadapted to receive a screw-driver.

5. In a panel lock, the combination of a
